The black clouds pressed down, and suddenly a strong wind blew up in all directions, blowing away most of the fog that shrouded the station.

On the wall that blocked the black devil, the bell rang and immediately spread throughout the station.

Everyone who was busy arranging the formation raised their heads and looked in the direction of the city wall.

"What's going on?"

"How do I feel the fog dissipating?"

"I feel it too. ”

"This bell is coming from the city wall, a warning of the coming black devil!"

"But no, isn't the black devil gone?

Everyone talked about it, stopped what they were doing, and their eyes were in the direction of the city wall, and their hearts were worried.

Uzo Kai glanced at Hiraoka, "Hiraoka, you go and see what happened." With that, he turned his head again and looked at Wen Shu, "Frost Fairy, I'll leave the rest to you." ”

Wen Shu nodded.

A trace of worry flashed on Bi Ningxin's face, but she immediately returned to her capable appearance.

She raised her chin and commanded a group of people from Huaqing Sect and Alchemy Sect with relatively high strength, asking them to put things away.

There are not many of their Yuan Crystals, only 230,000. If you use metacrystals to arrange the array, most of these metacrystals will be consumed, and it will be difficult to operate in the end.

Therefore, the best way is to set up a formation with people, so as to save spiritual power.

Bi Ningxin is responsible for the most critical part, and Yuzang Qi is responsible for the secondary part, although the two have never cooperated, but in a short period of time, after the two of them seriously discussed the formation diagram, there was basically no problem in cooperation.

Pinggang was extremely fast, and went to the city wall first. Wen Shu's movements were not slow, and she followed closely behind him.

"So many black devils!" Pinggang landed on the city wall, and when he looked down, he was surprised.

"What's going on?" Wen Shu was also startled, summoned the person on duty, and asked carefully.

The people on duty are one disciple of the Alchemy Sect and one disciple of the Huaqing Sect.

As soon as the disciples of the Alchemy Sect saw Wen Shu coming, they seemed to have found a backer and quickly told what they saw.

"Uncle Wen, two women suddenly appeared in the sky just now, and the two women flew in the air one left and one right, holding two fans and fanning them twice in the air, and the mist dispersed.

After the fog lifted, many black demons appeared in the soil in the distance, and their movements were very fast, and they flew over at once. ”

"Then why haven't they come here yet?" Wen Shu frowned and watched.

According to them, the two of them had blown away the fog in the air, and it was best to let those black devils directly enter the city wall, but now those black devils were still five hundred meters away, and there was still some distance to go.

"The disciple didn't know that after the two women saw the alarm from our door, they left, as if they were waiting for our door to report the news. The disciple spoke with some uncertainty and expressed his conjecture.

Wen Shu frowned, "You mean, you rang the bell to warn, and they left?"

"Yes. ”

When Pinggang heard this, he also felt weird, squinted his eyes, and held back the irritability in his heart, "Could it be a plan to divert the tiger from the mountain?"

When they hear the warning, they will definitely take people away, and those people will not try to lead them here.

Wen Shu shook her head, "Not necessarily, I think they are more like they want to prevent me from arranging the formation." ”

As soon as Pinggang heard this, the thoughts in his mind turned twice, "There are still spies among our people!"

"That's true. Wen Shu nodded.

If these people are really trying to stall for time, then there must be spies.

This formation had only been proposed for a long time, but those who controlled the black devil knew their countermeasures, saying that there were no spies, and they didn't believe it.

The shadow transmission formations in the station were all dismantled by Bi Ningxin, and an anti-tracking one was also set up, as long as that formation was activated, they could feel it.

Pinggang was furious, "It's time for these people to dare to leak the news! Have they all forgotten the oath they made when they entered the school?"

Wen Shu didn't reply, but looked at the sky and pondered. Her eyes were still covered by a strap, and the knot that helped floated with the wind.

The mist was surging above the city walls, and the martial mist, which used to be only shallow and had no feeling, was now much thicker.

She stretched out her hand to feel it, and said, "Pinggang Daoyou, I'm sorry for you to stay here first." ”

Pinggang nodded, "Hmm." ”

In Huaqingzong's station, the place where the formation was arranged was very quiet. Everyone was attentive to remembering the message Bi Ningxin had given them.

They were sitting cross-legged on the ground, Bi Ningxin was carving the formation, and buckets of beast blood were carried in by the rest of the disciples, and in less than a few seconds, they were carried out.

Bi Ningxin is holding a huge human-high pen in her hand, the pen shaft is made of three hundred years of jade bamboo, and the nib is made of the softest hair on Wolverine's belly, and the nib alone uses the hair of three Wolverine.

The pen was inserted into the half-human-high bucket, and the bright red and viscous blood disappeared without a trace in a matter of seconds.

I saw Bi Ningxin holding a pen and flicking it on the ground, the time of one stroke seemed to be fast, but it took at least five minutes.

And every stroke, Bi Ningxin has to use a bucket of beast blood to depict, and the demand for beast blood is huge.

"The blood is gone, quick! Seeing that another bucket of beast blood was gone, Wen Qian couldn't help but worry.

The formation had only been completed by less than a third, but the beast blood had already consumed as many as a hundred barrels. These beast blood were all the blood of intermediate spirit beasts, and even if their inventory was large, it was only one hundred and fifty barrels, which was estimated to be a little less.

He commanded, thinking about what to do with the blood he needed later.

Bi Ningxin was not disturbed by the outside world, calmly portraying the formation, but the sweat on her forehead and her lips that were already faintly trembling revealed her physical condition.

Wen Qian quickly stepped forward and helped her wipe her sweat, and then pulled the bucket of beast blood closer.

This formation can only be drawn by Bi Ningxin alone, one is for the coherence of the formation, and the other is for the success rate.

Uzo Kai organized the disciples of the Huaqing Sect, "Have you all memorized the formation?"

"Remember!" said everyone in unison.

"Okay, remember, then let's rehearse first, don't use spiritual power, let's get the position done first!" Uzo Kai said.

Everyone promised.

Seeing Wen Shu coming back, Yuzang Qi's expression did not move, and he still organized everyone to practice the position.

Since he handed over the matter to Wen Shu, he would not interfere more. Of course, if Wen Shu didn't have the ability, he could only barely be distracted to do some things and manage it.

Wen Shu fell down and glanced at the audience.

Her consciousness swept around her, whether it was the ground, the sky, or even the earth, she carefully examined it.

There is no trace of any formation, so there are still spies.

Wen Shu didn't speak, but shuttled through the crowd full, as if she was very casual.

Many people can't help but be distracted. Is there anything okay over the city walls? Why are the Frost Fairies walking around here?

Wen Qian glanced at her, and Chuanyin asked, "What's wrong?"

Wen Shu glanced sideways slightly, "You pay attention to the reactions of those people, as well as the beast blood that moved over, there are spies in it." ”
